OG exemplary drawing
 
1. A surgical stapler, comprising:
a motor;
a motor power interrupt circuit coupled to the motor;
a power source connector coupled between the motor power interrupt circuit and the motor;
a knife operably coupled to and movable by an actuation of the motor;
a sensor to measure a real-time parameter of the knife; and
a processor coupled to the motor, the motor power interrupt circuit, and the sensor, wherein the processor is to:
monitor the real-time parameter of the knife, wherein the real-time parameter measured by the sensor comprises at least one of a real-time velocity of the knife, a real-time current of the motor, a real-time acceleration of the surgical stapler, or a real-time position of the knife;
compare the real-time parameter relative to a predetermined range of values to produce an output; and
supply an activation signal to the motor power interrupt circuit to disconnect the motor from the power source connector based on the output.
